Any suitable ineztus inttv be employed to rotate the i eetntrie shnlt 20, but preteritbly and in order that the ntpply of oil led to the benrings may be made dependent en the movement oi the parts being lubrieuted, I employ it eonneetion ior transmitting motion from the driving IHPtlttlIliHit! of the nmehine. designed to be luhrieuted. To this end the shaft 26 has fixed thereon a worm gear 29 whieh meshes with und. is driven by it \vorin shalt 1-30. This worm shaft is disposed horizontally and is journnled at its front end in a bearing 3 on the front wall oi the reservoir, While its other end is journuled in ti sleeve .12 set into the rear "all of the tank,

this sleeve being seemed in place by means of bolts 33 {new through the wall of the tank and lugs Zl-l formed eve, nuts 35 being provided to set'urelv elznnp Suitable peeking is provided [or on the the sleeve in phtee.

the aperturtm in the Wall of the'lank through which the bearing sleeve and securing screws puss and the outer end of the sleeve is provided with a 1)Ll.\"l l.l\f f gland 36 which is held in position by nuts 37 threading on the 5 ends of the bolts 33 which also extend through lugs 38 projecting from the said gland. in order to prevent longitudinal movement ol' the worm shalt 30 the latter is provided with a shoulder ll) which abuls ugainst the inner end of the beariugsleeve 22 and is formed by reducing the end of the shaft pt ..in;i' through the said sleeve. The rear end of the worm'shalt it) extends beymid the rear wall of the tank untl is provided with a a suitable means, such as the belt wheel 3t to which motion is communicated from the driving mechanism be ing lubr' tiled. Suitable packing such as 40 is pro vided tor the pump barrel to prevent oil leaking bitch pal-1c the piston into the tank.

Means urn provided for varying the stroke of the pump pistoirin order to vary the rate of feed of the pump. To this ent'lone of the arms ol' the yol: 25, in the present instance that adjacent to the. trout wall oi the tank and indicated by the numeral 41, is inclined 0r beveled on its inner face and reacts with a sliding block or wedge "113, the lure of which adjacent the arm 4] is inclined or beveled reversely thereto. The l)ltit'l& 42 is adapted to slide on the arm ll and in order to pre vent disengagement therefrom it is provided with a tin 43 which tits in a guide \ray. shown in dotted lines in lg. 13, on the adjacent. face of the arm -11. The blot-l; 3O 421's supported by a stem orrod +1 whit'h purses through the arm -ll and the upper end of \vhich passeulhrough {L11 aperture in the cover I l and is threaded to receive an adjusting nut 45, the said aperture being of greater diameter than the stem so that the latter nnty I'Ui'li or oscillate freely as the piston ZZ-t is reeiprtrented. "he stein 44 iii pivotully'connected lo the wedge block 42, as shown in dolled lines in Fig. ii, in order to aeeonnnw (latte the block to this rocking movement of the. stem. The not t is provided with a recess on its under face lo reeeive a pin 4t; lined tothe (over ll to hold the nut against accidental rotation, while the latter is readily disenguged from the pin when it is desired. to adjust the block by lifting the nut slightly. With the wedge block 42 in the position shown in Fig. 2;, that is to my 45 in its elevated position, the ecccntritturns l'reely between the block 42 and the opposite arm of the yoke but all lost. play is eliminated and the pislon is given its full utroke. To shorten the stroke of the piston the nut 15 s turned so as to lower the block, which owinp to the inclined litt'ttti of the block and urns 4] provides lost motion between the yoke and eveentric, 'ltlt'll lost motion may be varied at will. By lowering the l)lt)('l( liar enough the pump may be thrown entirely out. of action.

The oil is discharged by the pump through t tube 47 which is in threaded engitgemei'it with the upper end of the tube 18 and this tube leads to a feed pipe 48 which conveys the oil to the butt ingto be li!l)ll(f"\i.0 l. This tube t? .isprovidod with a blender-test by a lateral brunt-h tube 48 which discharges downwardly through a sight. feed glasu 50 opening at its lower end through the top of the lid, ttltll the passage through the branch tube is opened and closed by it set-en valve 5%. 'l

no upper end of the tube 17 has its bore enlargedto previde a seat for gravity valve 52 normally closing the PASSQ"G through the said tube.

The tanknuiy be supported in any suitable manner. When employed with an automobile it is preferably curried by the dash board thereof, as shown in Fig. 3, and is lee-tiled in sut li position us to be within convenient. reach of the chauffer or driver. When so employed t he dash board as 53, is provided with an opening 54, through which the end of the worm shaft 30 passes, and also with an opening 55 through which etttfll of the feed pipes 48 passes. In order to permit of the removal of the rover oi the tank the tubes 47 are arranged to be readily disconnected from the feed pipes. To this end each tube 47 has its upper and screw threaded and the interior of its upper end is of a hollow eone shape, to cooperate with the eonieal end of a joint 56 by which the tube 47 is joined to an elbow 57 on the inner face of thev dash board and into which the feed pipe 47 is screwed. A nut 58 serves to hold the joint and tube 47 securely together but permits these parts to be readily separated. The openings 55, through which the feed pipes 48 extend, are elongated vertically for it purpose to be hereinafter explained.

Itv in to be understood that when a plurality of pumps is employed each pump is constructed and mounted in the manner heretofore described and is entirely separate from and independent of the other or others, except that the eeeentric shaft is common to all the pumps and passes through the piston yoke of each pump as shown in Fig. 3. The tank is provided with a filling strainer 59 carried by the cover and closed by a plug (it) in the usual manner; and it also has a gage glass (31 opening its bottom into the tank, for indicating the quantity of oil in the tank.

In operation, a slow reeiprocatting movement imparted to the piston of ezwh pump, the speed depending on the speed of the part from which motion is derived. is the piston moves on its out. or suction stroke oil is stacked up through the tube H, past the valve it and enters the pump barrel. Upon the discharge or in st rolze oi the piston the viilve it; is pressed to its seat and the valve 2 raised so that the oil is forced through the tube in and past the valves 21 and 52 and out of the teed pipe 48 to the bearing. the feed pipe beingnormally lull owing to the valve 21 which, upon the suction or outstrolie of the piston, falls back to its seat and prevents the (ill in the feed pipe from flowing back into the pump barrel.

(then it. is desired to ascertain the rate offeed, the bleeder valve 5l is opgied and the valve 52 being held to its seat by the pressure of oil in the feed pipe, the oil form-d out. by the pump passes into the branch pipe 49 and drops back into the tank through the glass 50 whit-h is so loeated as to be readily observable by the attendant; 'lhis sight feed is particularly useful for indicating when the desired rate of feed has been secured by the adjustment. ollhe wedge block of the pump.

All of the operative parts of the pumps proper being curried. by the cover and the yokes bolngso cousl ructed its to readily slip vertically oil the eccentric shaft, ll pumps, yokes: and adjusting devices may be ,remlii etl from the tool: by simply unscrewing the lid. uncoupis: the connections 56 and sliding the elbows 57 up r-vardly, this being permitted by the elongated Sluts 55 the shai't, M a

amass through which the feed pipes pans, and then merely lifting the cover upw rally oil the tank. This avoids the nec ity of detaching the pumps separatel and of disassembling the lll(t.llzl.lll5lll oi the pumps then).-

limping thorn entirely free from dust and dirt and insuring thorough lul n'i. ,n of the parts.
